重庆市30m土地覆被耕地类型数据（2010年）

重庆市30m土地覆被耕地类型数据（2010年），以中国土地覆被产品2010（ChinaCover2010）为底图栅格化完成。ChinaCover2010是以国产环境星遥感数据为主要数据源，辅以中华人民共和国植被图（1:1,000,000）、2000和2005年土地利用图及ASTERDEM生成的坡度和坡向数据等，采用面向对象技术实现解译。
分类系统的一级类与IPCC系统保持一致共6类，二级类采用了由FAO的LCCS生成的具有全球统一代码的38个类型，目前ChinaCover2010产品精度一级类可达到91%，二级类约为82%。

Chongqing 30m Land Cover Cropland Type Dataset (2010) was completed by rasterizing the China Land Cover Product 2010 (ChinaCover2010) as the base map. ChinaCover2010 takes China-made environmental satellite remote sensing data as its primary data source, supplemented by the Vegetation Map of the People's Republic of China (1:1,000,000 scale), land use maps from 2000 and 2005, and slope and aspect data derived from ASTER DEM, etc. It realizes land cover interpretation using object-oriented technology. The first-level categories of its classification system are consistent with the IPCC classification system, totaling 6 types. The second-level categories adopt 38 types with globally unified codes generated by the Food and Agriculture Organization of the United Nations (FAO)'s Land Cover Classification System (LCCS). Currently, the overall accuracy of the first-level categories of the ChinaCover2010 product reaches 91%, while that of the second-level categories is approximately 82%.
